U20EA Austin-healey 3000 OBD Code

OBD/2 U20EA error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code U20EA

Circuit High Input codes like U20EA are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

If your mirror switch assembly circuit failure check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U20EA and engine control unit are in charge of monitoring a bunch of different mirror switch assembly circuit failure, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Austin-healey 3000 U20EA OBD2 Code

A common cause of code U20EA is the failure of Mirror Switch Assembly Circuit Failure, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
Continuous oil flow to the VCT piston chamber
Improper ignition timing
Oil flow restriction in the oil passages or the VCT valve body

U20EA is a kind of Network Trouble Code

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
